- * Introduction
- * ************
- *
- * The following notes assume that you are familiar with the YAML specification
- * (http://yaml.org/spec/cvs/current.html).  We mostly follow it, although in
- * some cases we are less restrictive that it requires.
- *
- * The process of transforming a YAML stream into a sequence of events is
- * divided on two steps: Scanning and Parsing.
- *
- * The Scanner transforms the input stream into a sequence of tokens, while the
- * parser transform the sequence of tokens produced by the Scanner into a
- * sequence of parsing events.
- *
- * The Scanner is rather clever and complicated. The Parser, on the contrary,
- * is a straightforward implementation of a recursive-descendant parser (or,
- * LL(1) parser, as it is usually called).
- *
- * Actually there are two issues of Scanning that might be called "clever", the
- * rest is quite straightforward.  The issues are "block collection start" and
- * "simple keys".  Both issues are explained below in details.
- *
- * Here the Scanning step is explained and implemented.  We start with the list
- * of all the tokens produced by the Scanner together with short descriptions.
- *
- * Now, tokens:
- *
- *      STREAM-START(encoding)          # The stream start.
- *      STREAM-END                      # The stream end.
- *      VERSION-DIRECTIVE(major,minor)  # The '%YAML' directive.
- *      TAG-DIRECTIVE(handle,prefix)    # The '%TAG' directive.
- *      DOCUMENT-START                  # '---'
- *      DOCUMENT-END                    # '...'
- *      BLOCK-SEQUENCE-START            # Indentation increase denoting a block
- *      BLOCK-MAPPING-START             # sequence or a block mapping.
- *      BLOCK-END                       # Indentation decrease.
- *      FLOW-SEQUENCE-START             # '['
- *      FLOW-SEQUENCE-END               # ']'
- *      BLOCK-SEQUENCE-START            # '{'
- *      BLOCK-SEQUENCE-END              # '}'
- *      BLOCK-ENTRY                     # '-'
- *      FLOW-ENTRY                      # ','
- *      KEY                             # '?' or nothing (simple keys).
- *      VALUE                           # ':'
- *      ALIAS(anchor)                   # '*anchor'
- *      ANCHOR(anchor)                  # '&anchor'
- *      TAG(handle,suffix)              # '!handle!suffix'
- *      SCALAR(value,style)             # A scalar.
- *
- * The following two tokens are "virtual" tokens denoting the beginning and the
- * end of the stream:
- *
- *      STREAM-START(encoding)
- *      STREAM-END
- *
- * We pass the information about the input stream encoding with the
- * STREAM-START token.
- *
- * The next two tokens are responsible for tags:
- *
- *      VERSION-DIRECTIVE(major,minor)
- *      TAG-DIRECTIVE(handle,prefix)
- *
- * Example:
- *
- *      %YAML   1.1
- *      %TAG    !   !foo
- *      %TAG    !yaml!  tag:yaml.org,2002:
- *      ---
- *
- * The correspoding sequence of tokens:
- *
- *      STREAM-START(utf-8)
- *      VERSION-DIRECTIVE(1,1)
- *      TAG-DIRECTIVE("!","!foo")
- *      TAG-DIRECTIVE("!yaml","tag:yaml.org,2002:")
- *      DOCUMENT-START
- *      STREAM-END
- *
- * Note that the VERSION-DIRECTIVE and TAG-DIRECTIVE tokens occupy a whole
- * line.
- *
- * The document start and end indicators are represented by:
- *
- *      DOCUMENT-START
- *      DOCUMENT-END
- *
- * Note that if a YAML stream contains an implicit document (without '---'
- * and '...' indicators), no DOCUMENT-START and DOCUMENT-END tokens will be
- * produced.
- *
- * In the following examples, we present whole documents together with the
- * produced tokens.
- *
- *      1. An implicit document:
- *
- *          'a scalar'
- *
- *      Tokens:
- *
- *          STREAM-START(utf-8)
- *          SCALAR("a scalar",single-quoted)
- *          STREAM-END
- *
- *      2. An explicit document:
- *
- *          ---
- *          'a scalar'
- *          ...
- *
- *      Tokens:
- *
- *          STREAM-START(utf-8)
- *          DOCUMENT-START
- *          SCALAR("a scalar",single-quoted)
- *          DOCUMENT-END
- *          STREAM-END
- *
- *      3. Several documents in a stream:
- *
- *          'a scalar'
- *          ---
- *          'another scalar'
- *          ---
- *          'yet another scalar'
- *
- *      Tokens:
- *
- *          STREAM-START(utf-8)
- *          SCALAR("a scalar",single-quoted)
- *          DOCUMENT-START
- *          SCALAR("another scalar",single-quoted)
- *          DOCUMENT-START
- *          SCALAR("yet another scalar",single-quoted)
- *          STREAM-END
- *
- * We have already introduced the SCALAR token above.  The following tokens are
- * used to describe aliases, anchors, tag, and scalars:
- *
- *      ALIAS(anchor)
- *      ANCHOR(anchor)
- *      TAG(handle,suffix)
- *      SCALAR(value,style)
- *
- * The following series of examples illustrate the usage of these tokens:
- *
- *      1. A recursive sequence:
- *
- *          &A [ *A ]
- *
- *      Tokens:
- *
- *          STREAM-START(utf-8)
- *          ANCHOR("A")

- *          ALIAS("A")
- *          FLOW-SEQUENCE-END
- *          STREAM-END
- *
- *      2. A tagged scalar:
- *
- *          !!float "3.14"  # A good approximation.
- *
- *      Tokens:
- *
- *          STREAM-START(utf-8)
- *          TAG("!!","float")
- *          SCALAR("3.14",double-quoted)
- *          STREAM-END
- *
- *      3. Various scalar styles:
- *
- *          --- # Implicit empty plain scalars do not produce tokens.
- *          --- a plain scalar
- *          --- 'a single-quoted scalar'
- *          --- "a double-quoted scalar"
- *          --- |-
- *            a literal scalar
- *          --- >-
- *            a folded
- *            scalar
- *
- *      Tokens:
- *
- *          STREAM-START(utf-8)
- *          DOCUMENT-START
- *          DOCUMENT-START
- *          SCALAR("a plain scalar",plain)
- *          DOCUMENT-START
- *          SCALAR("a single-quoted scalar",single-quoted)
- *          DOCUMENT-START
- *          SCALAR("a double-quoted scalar",double-quoted)
- *          DOCUMENT-START
- *          SCALAR("a literal scalar",literal)
- *          DOCUMENT-START
- *          SCALAR("a folded scalar",folded)
- *          STREAM-END
- *
- * Now it's time to review collection-related tokens. We will start with
- * flow collections:
- *
- *      FLOW-SEQUENCE-START
- *      FLOW-SEQUENCE-END
- *      FLOW-MAPPING-START
- *      FLOW-MAPPING-END
- *      FLOW-ENTRY
- *      KEY
- *      VALUE
- *
- * The tokens FLOW-SEQUENCE-START, FLOW-SEQUENCE-END, FLOW-MAPPING-START, and
- * FLOW-MAPPING-END represent the indicators '[', ']', '{', and '}'
- * correspondingly.  FLOW-ENTRY represent the ',' indicator.  Finally the
- * indicators '?' and ':', which are used for denoting mapping keys and values,
- * are represented by the KEY and VALUE tokens.
- *
- * The following examples show flow collections:
- *
- *      1. A flow sequence:
- *
- *          [item 1, item 2, item 3]
- *
- *      Tokens:
- *
- *          STREAM-START(utf-8)
- *          FLOW-SEQUENCE-START
- *          SCALAR("item 1",plain)
- *          FLOW-ENTRY
- *          SCALAR("item 2",plain)
- *          FLOW-ENTRY
- *          SCALAR("item 3",plain)
- *          FLOW-SEQUENCE-END
- *          STREAM-END
- *
- *      2. A flow mapping:
- *
- *          {
- *              a simple key: a value,  # Note that the KEY token is produced.
- *              ? a complex key: another value,
- *          }
- *
- *      Tokens:
- *
- *          STREAM-START(utf-8)
- *          FLOW-MAPPING-START
- *          KEY
- *          SCALAR("a simple key",plain)
- *          VALUE
- *          SCALAR("a value",plain)
- *          FLOW-ENTRY
- *          KEY
- *          SCALAR("a complex key",plain)
- *          VALUE
- *          SCALAR("another value",plain)
- *          FLOW-ENTRY
- *          FLOW-MAPPING-END
- *          STREAM-END
- *
- * A simple key is a key which is not denoted by the '?' indicator.  Note that
- * the Scanner still produce the KEY token whenever it encounters a simple key.
- *
- * For scanning block collections, the following tokens are used (note that we
- * repeat KEY and VALUE here):
- *
- *      BLOCK-SEQUENCE-START
- *      BLOCK-MAPPING-START
- *      BLOCK-END
- *      BLOCK-ENTRY
- *      KEY
- *      VALUE
- *
- * The tokens BLOCK-SEQUENCE-START and BLOCK-MAPPING-START denote indentation
- * increase that precedes a block collection (cf. the INDENT token in Python).
- * The token BLOCK-END denote indentation decrease that ends a block collection
- * (cf. the DEDENT token in Python).  However YAML has some syntax pecularities
- * that makes detections of these tokens more complex.
- *
- * The tokens BLOCK-ENTRY, KEY, and VALUE are used to represent the indicators
- * '-', '?', and ':' correspondingly.
- *
- * The following examples show how the tokens BLOCK-SEQUENCE-START,
- * BLOCK-MAPPING-START, and BLOCK-END are emitted by the Scanner:
- *
- *      1. Block sequences:
- *
- *          - item 1
- *          - item 2
- *          -
- *            - item 3.1
- *            - item 3.2
- *          -
- *            key 1: value 1
- *            key 2: value 2
- *
- *      Tokens:
- *
- *          STREAM-START(utf-8)
- *          BLOCK-SEQUENCE-START
- *          BLOCK-ENTRY
- *          SCALAR("item 1",plain)
- *          BLOCK-ENTRY
- *          SCALAR("item 2",plain)
- *          BLOCK-ENTRY
- *          BLOCK-SEQUENCE-START
- *          BLOCK-ENTRY
- *          SCALAR("item 3.1",plain)
- *          BLOCK-ENTRY
- *          SCALAR("item 3.2",plain)
- *          BLOCK-END
- *          BLOCK-ENTRY
- *          BLOCK-MAPPING-START
- *          KEY
- *          SCALAR("key 1",plain)
- *          VALUE
- *          SCALAR("value 1",plain)
- *          KEY
- *          SCALAR("key 2",plain)
- *          VALUE
- *          SCALAR("value 2",plain)
- *          BLOCK-END
- *          BLOCK-END
- *          STREAM-END
- *
- *      2. Block mappings:
- *
- *          a simple key: a value   # The KEY token is produced here.
- *          ? a complex key
- *          : another value
- *          a mapping:
- *            key 1: value 1
- *            key 2: value 2
- *          a sequence:
- *            - item 1
- *            - item 2
- *
- *      Tokens:
- *
- *          STREAM-START(utf-8)
- *          BLOCK-MAPPING-START
- *          KEY
- *          SCALAR("a simple key",plain)
- *          VALUE
- *          SCALAR("a value",plain)
- *          KEY
- *          SCALAR("a complex key",plain)
- *          VALUE
- *          SCALAR("another value",plain)
- *          KEY
- *          SCALAR("a mapping",plain)
- *          BLOCK-MAPPING-START
- *          KEY
- *          SCALAR("key 1",plain)
- *          VALUE
- *          SCALAR("value 1",plain)
- *          KEY
- *          SCALAR("key 2",plain)
- *          VALUE
- *          SCALAR("value 2",plain)
- *          BLOCK-END
- *          KEY
- *          SCALAR("a sequence",plain)
- *          VALUE
- *          BLOCK-SEQUENCE-START
- *          BLOCK-ENTRY
- *          SCALAR("item 1",plain)
- *          BLOCK-ENTRY
- *          SCALAR("item 2",plain)
- *          BLOCK-END
- *          BLOCK-END
- *          STREAM-END
- *
- * YAML does not always require to start a new block collection from a new
- * line.  If the current line contains only '-', '?', and ':' indicators, a new
- * block collection may start at the current line.  The following examples
- * illustrate this case:
- *
- *      1. Collections in a sequence:
- *
- *          - - item 1
- *            - item 2
- *          - key 1: value 1
- *            key 2: value 2
- *          - ? complex key
- *            : complex value
- *
- *      Tokens:
- *
- *          STREAM-START(utf-8)
- *          BLOCK-SEQUENCE-START
- *          BLOCK-ENTRY
- *          BLOCK-SEQUENCE-START
- *          BLOCK-ENTRY
- *          SCALAR("item 1",plain)
- *          BLOCK-ENTRY
- *          SCALAR("item 2",plain)
- *          BLOCK-END
- *          BLOCK-ENTRY
- *          BLOCK-MAPPING-START
- *          KEY
- *          SCALAR("key 1",plain)
- *          VALUE
- *          SCALAR("value 1",plain)
- *          KEY
- *          SCALAR("key 2",plain)
- *          VALUE
- *          SCALAR("value 2",plain)
- *          BLOCK-END
- *          BLOCK-ENTRY
- *          BLOCK-MAPPING-START
- *          KEY
- *          SCALAR("complex key")
- *          VALUE
- *          SCALAR("complex value")
- *          BLOCK-END
- *          BLOCK-END
- *          STREAM-END
- *
- *      2. Collections in a mapping:
- *
- *          ? a sequence
- *          : - item 1
- *            - item 2
- *          ? a mapping
- *          : key 1: value 1
- *            key 2: value 2
- *
- *      Tokens:
- *
- *          STREAM-START(utf-8)
- *          BLOCK-MAPPING-START
- *          KEY
- *          SCALAR("a sequence",plain)
- *          VALUE
- *          BLOCK-SEQUENCE-START
- *          BLOCK-ENTRY
- *          SCALAR("item 1",plain)
- *          BLOCK-ENTRY
- *          SCALAR("item 2",plain)
- *          BLOCK-END
- *          KEY
- *          SCALAR("a mapping",plain)
- *          VALUE
- *          BLOCK-MAPPING-START
- *          KEY
- *          SCALAR("key 1",plain)
- *          VALUE
- *          SCALAR("value 1",plain)
- *          KEY
- *          SCALAR("key 2",plain)
- *          VALUE
- *          SCALAR("value 2",plain)
- *          BLOCK-END
- *          BLOCK-END
- *          STREAM-END
- *
- * YAML also permits non-indented sequences if they are included into a block
- * mapping.  In this case, the token BLOCK-SEQUENCE-START is not produced:
- *
- *      key:
- *      - item 1    # BLOCK-SEQUENCE-START is NOT produced here.
- *      - item 2
- *
- * Tokens:
- *
- *      STREAM-START(utf-8)
- *      BLOCK-MAPPING-START
- *      KEY
- *      SCALAR("key",plain)
- *      VALUE
- *      BLOCK-ENTRY
- *      SCALAR("item 1",plain)
